The sole pad can include one or more enclosures that are at least partially positioned beneath the parts of the sole of the user's foot. For example, the sole pad can include one or more toe enclosures, one or more ball of a foot enclosures, one or more inner arch enclosures, one or more outer upper arch enclosures, one or more outer lower arch enclosures, and one or more heel enclosures.

FIG. 1 is the bottom view of the sole pad 2. The one or more toe enclosures 4 can at least partially lie beneath the user's toes or phalanges. In an aspect, the one or more toe enclosures 4 at least partially lie beneath the 14 bones (i.e., the two in the big toe and the three in each of the other four toes) called phalanges. The one or more toe enclosures 4 can be one, two, three, four, five, six, seven, or eight toe enclosures. In an example, the one or more toe enclosures 4 can be just one enclosure that at least partially lies beneath all of the user's toes or phalanges. FIG. 1 depicts just one toe enclosure 4 lying beneath all of the toes of the user. In another example, the one or more toe enclosures can be five separate toe enclosures that at least partially lie beneath each of the user's toes separately. The one or more ball of the foot enclosures 6 at least partially lie beneath the ball of the user's foot. More particularly, the one or more ball of the foot enclosures 6 at least partially lie beneath the heads of the metatarsals where the toes join the rest of the foot. The one or more ball of the foot enclosures 6 can be one, two, three, four, five, six, seven, or eight ball of the foot enclosures. FIG. 1 depicts just one ball of the foot enclosure 6. The one or more inner arch enclosures 10 at least partially lie beneath the inner arch area of the foot. In an aspect, the one or more inner arch enclosures 10 at least partially lie beneath the medial arch of the user's foot. In another aspect, the one or more inner arch enclosures 10 at least partially lie beneath the calcaneus, the talus, the navicular, the three cuneiforms, and the first, second, and third metatarsals. The one or more inner arch enclosures 10 can be one, two, three, four, five, six, seven, or eight inner arch enclosures. FIG. 1 depicts just one inner arch enclosures 10. The one or more outer upper arch enclosures 8 at least partially lie beneath the outer upper arch area of the foot. In an aspect, the one or more outer upper arch enclosures 8 at least partially lie beneath the lateral arch of the user's foot. In another aspect, the one or more outer upper arch enclosures 8 at least partially lie beneath the calcaneus, the cuboid, and the fourth and fifth metatarsals. The one or more outer upper arch enclosures 8 can be one, two, three, four, five, six, seven, or eight outer upper arch enclosures. FIG. 1 depicts one outer arch enclosure 8. The one or more lower upper arch enclosures 12 at least partially lie beneath the lower upper arch area of the foot. In an aspect, the one or more outer lower arch enclosures 12 at least partially lie beneath the lateral arch of the user's foot. In another aspect, the one or more outer lower arch enclosures 12 at least partially lie beneath the calcaneus, the cuboid, and the fourth and fifth metatarsals. The one or more outer lower arch enclosures 12 can be one, two, three, four, five, six, seven, or eight outer lower arch enclosures. The defining characteristic between the one or more outer upper arch enclosures 8 and the one or more outer lower arch enclosures 12 is that one or more outer upper arch enclosures 8 lies closer to the user's toes and the one or more outer lower arch enclosures 12 lies closer to the user's heel. In some embodiments, the one or more inner arch enclosures 10, the one or more outer upper arch enclosures 8, and the one or more lower upper arch enclosures 12 can have portions that at least partially extend across both the medial arch and the lateral arch of the user's foot. For example, FIG. 1 depicts one outer arch enclosure 8, which extends across both the lateral arch and the medial arch. Since the inner arch enclosures and the outer arch enclosures 8 can have portions that at least partially extend across both the lateral and medial arches, the defining characteristic between the outer and inner arch enclosures is whether the majority of the area for the enclosures lies beneath the medial arch or the lateral arch. An arch enclosure with the majority of its area under the medial arch is an inner arch enclosure. An arch enclosure with the majority of its area under the lateral arch is an outer arch enclosure. The one or more heel enclosures 14 at least partially lies beneath the heel of the user's foot.

For example, the sock and the sole pad can have infant's sizes from 000 to 13, children's sizes from 5 to 10, adult women's sizes 3 to 10, and adult men's sizes 6 to 14. The one or more toe enclosures 4, the one or more a ball of a foot enclosures 6, the one or more inner arch enclosures 10, the one or more outer arch enclosures 8, and the one or more heel enclosures 14 can be at least partially filled with a substrate to give the enclosures a thickness from a low of about 1 mm, about 5 mm, about 10 mm, or about 15 mm to a high about 30 mm, about 40 mm, about 50 mm, or about 60 mm. For example, the sole pad can have a thickness from about 1 mm to about 5 mm, about 2 mm to about 7 mm, about 5 mm to about 10 mm, about 8 mm to about 15 mm, about 12 mm to about 25 mm, about 15 mm to about 30 mm, about 20 mm to about 40 mm, about 30 mm to about 50 mm, about 35 mm to about 60 mm, about 40 mm to about 50 mm, about 40 mm to about 60 mm, or about 50 mm to about 60 mm.

With reference to the figures, FIG. 3 depicts a side view of an illustrative sock 16 containing the sole pad 2, which can be used for the envelopment of a user's lower leg, ankle and foot. According to some embodiments, the sock 16 can include, but is not limited to, a leg section 18 that encompasses at least a portion of the user's leg and ankle, an upper sock section 26 that encompasses the user's foot, a lower treading section 30 with a pocket 36, and a sole pad 2 that can be inserted into the pocket of the lower treading section.

The leg section 18 has tubular dimension and includes an opening 20 leading to a sock interior (not pictured). The leg section 18 can be elastic and flexible. The leg section 18 can include a cuff 22. The leg section 18 can include elastic 24 to help maintain the sock 16 in place around the user's leg. The leg section 18 lies adjacent to the upper sock section 26. The upper sock section has tubular dimension and is in communication the leg section 18. The leg section 18 and the upper sock section 26 can be made separately and sewn together or can be integrally formed, for example, during the knitting process of the sock. The upper sock section 26 and the leg section 18 can be formed by one or more seams 28. The upper sock section can be closed at an end with one or more seams at or near where the user's toes would be located.

The upper sock section 26 lies adjacent and above a lower treading section 30. The lower treading section 30 is made of at least two-plies of textile material. The at least two-plies of textile material has an at least upper ply 32 made of at least one ply of textile material and an at least lower ply 34 made of at least one ply of textile material. The at least upper ply 32 can be 2-ply, 3-ply, 4-ply, 5-ply, 6-ply, 7-ply, or 8-ply of textile material. The at least lower ply 34 can be 2-ply, 3-ply, 4-ply, 5-ply, 6-ply, 7-ply, or 8-ply of textile material.

A pocket 36 is formed between the upper ply 32 and the lower ply 34. A sole pad 2 can be placed into the pocket 36. For example, the lower treading section 30 can be formed from exactly two plies, i.e., the upper ply 32 and the lower ply 34, where the upper ply 32 lies adjacent and touches the sole of the user's foot and the lower ply 34 comes into contact with the ground when the user is walking, and where a pocket 36 formed by the space between the two plies that can contains a sole pad.

In a specific embodiment, the sock 16 can have in at least one of the plies of the lower treading section a slit 38 transverse to the central axis along the longer tubular dimension of the sock. The slit 38 allows for the insertion of the sole pad in the pocket between the at least two-plies of textile material of the treading section. The slit 38 can be in the upper ply 32. If the slit 38 is in the upper ply 38, the sock to be turned inside out to aid in insertion of the sole pad 2. The slit 38 can also be in the lower ply 34 of the treading section 30. If the slit 38 is in the lower ply 32, the sock 16 does not need to be turned inside out to aid in inserting of the sole pad.

In another specific embodiment, the sock 16 does not include a slit 38 and the sole pad 2 is integrally positioned into the pocket of the lower treading section during the manufacturing of the sock 16. In this embodiment, because there is no slit 38, the sole pad 2 is not replaceable.

The upper sock section 26 and the treading section 30 can be made separately and sewn together or can be integrally formed, for example, during the knitting process of the sock. The upper sock section 26 and the treading section 30 can be formed by one or more seams.

The sock 16 can be manufactured using any of the well-known methods and machines for making conventional socks, such as circular knitting machines. In one embodiment, a conventional sock can be used for constructing the sock 16. For example, a conventional sock can include a leg section 18, an upper sock section 26, and one ply of the lower treading section 32. The at least a second lower ply 34 of the treading section can be attached (sewn) to form the pocket for the sole pad.

The leg section 18, the upper sock section 26, the lower treading section 30, and the sole pad 2 can be made of one or more textile materials. For example, the one or more textile materials can include, but is not limited to: natural yarns, such as cotton and wool yarns, man-made yarns, such as viscose, polyester, nylon and polypropylene.

The lavender that can be used in the sole pad 2 can include, but is not limited to: Spanish, Kew Red Spanish, Yellow, Sweet, French, Allardii, Goodwin Creek Gray, Pinnata, and Woolly Lavender. The lavender can be native to the Mediterranean countries such as Italy, Spain, North Africa, Switzerland, and France. The various lavenders have different fragrance, size, color, texture, and flower heads. Spanish lavender has showy, richly colored bracts extending from the top of the flower head, which like all lavender, is made up of calyxes with tiny blossoms (corollas). The less showy pale mauve bracts of French lavender protrude only slightly above the flower head, and are cupped together more like praying hands.

The lavender can be cut and/or dried before being used in the sole pad 2. For example, the lavender can be harvested in bloom or at the end of the blooming season. The stalks with flower heads can be tied in bundles of from 30 to several hundred, then dried. Drying modes include air drying, oven drying, microwave drying, and freeze-drying. The most common process involves hanging bundles to dry in an inverted position in curing sheds or other facilities. The drying period ranges from several weeks to months, depending on the variety and the use, and the specific drying regimen, including heat and humidity. The dried bundles of lavender can be processed to remove the dried flower buds (corollas/calyxes) wherein the fragrance-containing essential oils are concentrated. The dried buds can be cut or snapped off the stems, and residual bracts, leaves and petals can be shaken out, with the buds being collected. The one or more lavender plant materials can be one, two, three, four, five, six, seven, or eight.

The composition of the gel can include, but is not limited to: water, propylene glycol and a superabsorbent polymer. The water can be of any suitable type, such as tap water or distilled water. The values given herein below are with regard to tap water, but other water can be used (e.g., purified, distilled, or de-ionized). The type of water used will likely affect the ratios of the other constituents.

The gel contained inside the sole pad 2 can be responsive to external heating or cooling that is applied to the sole pad 2. For example, the sole pad 2 can be heated in a microwave oven in one or more intervals of about twenty seconds each until a desired temperature is reached. Another example, the sole pad 2 can be heated by running hot tap water over it for from one to twenty minutes. For cooling, the sole pad 2 can be left in a conventional residential refrigerator and/or freezer until ready for use.

Despite being heated or cooled, the gel remains in a gel-like state whereby it provides cushioning means to the temperature pack even when heated or cooled. This cushioning can be used for the benefit of the foot to which the sole pad 2 is applied in the hot and/or cold therapy.

The propylene glycol can provide the flexibility that facilitates the cushioning effect of the gel even when cooled. The propylene glycol can be commercial grade; one supplier of this is Harcros Chemicals Inc. of Kansas City, Kans. Propylene glycol can include 1,2 propanediol; propanediol-1,2; and 1,2-dihydroxypropane.

In an embodiment, the water and propylene glycol are mixed in a ratio of about 13:3 by volume of water to propylene glycol. This mixture is then combined with the superabsorbent polymer in the ratio of about 192:1 by volume of mixture to polymer. This 192:1 ratio specifically applies to the aforementioned brand of crosslinked homopolymer of partially neutralized acrylic acid.

The superabsorbent polymer can include a crosslinked homopolymer of partially neutralized acrylic acid. One particular product that provides this is FAVOR® 210 from Stockhausen, Inc. of Greensboro, N.C. This is a crosslinked homopolymer of partially neutralized acrylic acid, some versions of which may contain a polyalcohol. Neutralization is accomplished with a sodium hydroxide solution. In its dry form, this particular product is a granular powder of crystalline structure. Upon swelling with water, it yields a gel-like suspension. The uptake of water is facilitated by the negative carboxylic groups of the polymer and their hydration with water molecules. The negative carboxylic groups give this brand of polymers a high negative surface charge. Due to its crosslinking, this brand of polymer is essentially insoluble in water. However, incomplete crosslinking results in small amounts of “water extracts” that can be leached out of the polymer matrix by water. High salt concentrations lead to reduced swelling capacity during gel formation and hence to smaller amounts of water extracts. Bivalent and trivalent cations can quickly exchange the sodium and bind themselves to the polymer via the negative carboxylic groups. This leads to shrinkage of the gel, which then becomes inert. Another supplier of a suitable superabsorbent polymer is Nalco Chemical Company of Naperville, Ill.
